The birds I feed in my back yard are varied in type. The feeder runs empty sometimes. I go get it and fill it with black oil sunflower seeds. One or two watch me take and fill it. Soon a large number arrive and feed. You don’t suppose Mable talks to Bulls, Tigers, Hammerheads and the sort do you? Are sharks as smart as birds or just hungry. I guess you could send your kids to Mexico, the sharks there are also hunters. Just wondering.
